This plugin hasnt been tested with the latest three major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

At WowPress.host company we regularly migrate very old databases and clean it up to make sure website using it is running smoothly. Those databases have all different kinds of inconsistencies collected during years or even decades of usage, and Media Library is the most common problematic piece of data here.
That plugin helps to solve most common problems related to Media Library data.

We use a lot of open-source tools in our work, and therefore decided publish our own tools so that those can be used by the community too.

Reviews

I had a corrupted Media Library. Images were on server but not the folders were missing from the media library.
By selecting just the main images (not the thumbnails) I was able to reimport them and the library now look as it should.
Hopefully that means it all works now.
NOTE: you need to change the default date to file date if are doing what I did.

I searched a long time to actually find a working plugin that would remove all the orphaned entries in a photographers website.
This worked very well!
Some suggestion to get it to 5 stars:
Make a short FAQ for how to do certain things. For me it was only important to fix the media library and remove all the orphaned files, so it would be nice to show the users which settings should be used for different usage cases, like for example:
Delete orphaned images
Delete images that are no longer used in the Website
Recreate the Metadata and Thumbnails

This plugin is legitimate. Works perfectly. Of course, with everything you do in WP related to the database and files; you should ALWAYS pull your own backups. However, I had no need to use them. It worked the first time and did a miracle for a client's site I was working on.
